Education: While these young men could have studied anywhere, both guys chose universities close to home. Wills chose Scotland's St. Andrews University over U.S. celeb-favorites like Harvard and Brown, and Kris passed on a scholarship to Duke to attend the University of Minnesota.

All-Around Athletes: Polo isn't William's only sporty pursuit—as a student, the prince enjoyed swimming, cross-country running and basketball. Of course, Kris knows a little something about hoops himself, but like Wills, he was also an avid swimmer growing up. At one point, the future Mr. Kardashian was the top 10-year-old in the U.S. in six competitive swimming trials, second only to a young Michael Phelps in the remaining events.
